Has Silverstone exposed Ferrari's development race fears?

Ferrari was second best to Mercedes at Silverstone on Friday - an increasingly regular trend at recent Formula 1 grands prix. But is it the gap to the team behind, instead of the Silver Arrows, that it should be worried about?

Once it was established that Ferrari was a serious threat to Mercedes at the start of the 2017 season, the big question was always whether it could keep up the development pace. Based on the evidence of Friday practice at Silverstone, the doubts remain and there will be some furrowed brows in the Ferrari garage.

Silverstone is a slightly unusual circuit, with ultra-fast corners like Copse, Becketts/Maggotts and Abbey posing a different challenge for the 2017 breed of F1 cars. While the average speed of Silverstone is actually slightly slower than what we saw in Austria last week, no track has been so demanding of high-speed poise.
